SONOFF Zigbee Temperature & Humidity Display Sensor

Real-Time Temperature & Humidity Monitoring

The SONOFF SNZB-02D is a Zigbee 3.0 Temperature and Humidity Display Sensor designed to provide clear, accurate monitoring of your indoor environment. Its built-in LCD screen lets you see the current temperature and humidity directly on the device, while a compatible Zigbee gateway enables remote monitoring through the app.

Large 2.8″ LCD Display

The SNZB-02D features a large 2.8-inch LCD display that makes temperature and humidity readings easy to see at a glance. The screen also provides useful information such as battery status and room-condition indicators.

High-Accuracy Swiss-Made Sensor

A Swiss-made sensor provides accurate indoor climate measurements, with temperature accuracy of ±0.2°C / ±0.4°F and humidity accuracy of ±2% RH. This makes the SNZB-02D suitable for monitoring rooms where maintaining comfortable temperature and humidity levels is important.

Fast 5-Second Refresh Rate

When temperature or humidity changes, the SNZB-02D can report updated readings at intervals as short as 5 seconds. This allows your smart home system to respond quickly to changes in environmental conditions.

Remote Monitoring & Smart Alerts

When paired with a compatible Zigbee gateway, you can monitor temperature and humidity remotely through the app. Alerts can also be configured when temperature or humidity moves outside your selected comfort range.

Historical Data & Export

The SNZB-02D supports up to six months of cloud data storage through the supported SONOFF ecosystem. Historical readings can be reviewed, including hourly trends and high and low readings, with data export available for further analysis.

Zigbee 3.0 Smart Home Connectivity

The SNZB-02D uses Zigbee 3.0 and requires a compatible Zigbee gateway or coordinator. It can be integrated into compatible smart-home systems and used as a trigger for automated scenes.

Smart Scene Automation

Temperature and humidity readings can be used to trigger smart-home automations. For example, the sensor can be used to trigger a compatible humidifier when humidity drops below a selected level, helping automate indoor climate management.

Three Flexible Mounting Options

The SNZB-02D can be placed on a desk using its built-in stand, attached magnetically to a suitable metal surface, or mounted using the supplied 3M adhesive base. This provides flexibility when positioning the sensor around your home or office.

Voice Assistant Compatibility

With compatible smart-home integrations, temperature and humidity information can be accessed through supported voice assistants such as Alexa and Google Home. SONOFF also supports integration of Zigbee devices into Apple Home through a compatible Matter Bridge.

Wireless Battery-Powered Design

The SNZB-02D is powered by a CR2450 3V battery, allowing it to be installed without a permanent power connection. Its compact wireless design makes it suitable for flexible indoor placement.

Ideal for Smart Home Climate Monitoring

Use the SONOFF SNZB-02D in bedrooms, living rooms, offices, nurseries, storage areas and other indoor spaces where you want an easy way to monitor temperature and humidity. It can also become part of automated smart-home routines using compatible Zigbee devices.

Important Note

The SNZB-02D is a Zigbee device and is not a standalone WiFi sensor. A compatible Zigbee gateway or coordinator is required for app monitoring, notifications and smart-home automation.
